Embodiment 1
[0026] According to the molar ratio of silver nitrate and bismuth nitrate in the reaction mixture is 1:1, take 30ml of 20mM silver nitrate solution and add dropwise to 40ml of 20mM melamine solution, let stand for 3h to form solution A; dissolve 0.070g of ammonium metavanadate in 25ml of 1M Solution B was obtained in sodium hydroxide solution; AB was mixed and stirred for 1 hour to obtain solution C; 0.291g of bismuth nitrate pentahydrate was dissolved in 50ml of 1M dilute nitric acid solution and stirred to obtain clear solution D; CD was mixed and mixed with 1M sodium hydroxide The solution was adjusted to neutral and stirred rapidly for 1h. Separation by filtration, washing with deionized water three times, washing with absolute ethanol once, and drying at 80°C for 6 hours to obtain the precursor.
[0027] Put the obtained precursor in a ceramic dry pot with a cover, then put the dry pot in a muffle furnace to bake, control the heating rate at 5°C / h, rise from room temperat...
